ELECTRIC HEATER FOR PERMANENT-WAVING MACHINES.

Application led October 19, 1922. Serial No. 595,522.

To all whom t may concer/n.'

Be it known that I, GABRIEL LANTIERI, residing at Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in an Electric Heater for Permanent-Taving Machines, of which the following is a specilication.

This invention relates to electric heating devices, and more particularly to an electric heater adapted for use in what is known as permanent hair waving.

One of the objects of the invention is to provide a heater of the above character, which is simple and compact, and so constructed that it is not likely to get out o f order.

Another object of the invention is to provide aY heater which is light in weight, and so formed that a number of heaters positioned upon the head of the subject whose hair is being waved, will occupy a minimum amount of space, thereby enabling a relatively greater number of heaters to be assembled upon the head of the subject than has been possible in heaters as hitherto constructed.

Other objects and aims of the invention, more or less specific than those referred to above, will be in part obvious and in part pointed out in the course of the following description of the elements, combinations,

arrangements of parts and applications ofV principles, constituting the invention; and

the scope of protection contemplated will be indicated in the appended claims.

In the accompanying drawing, wherein I have illustrated preferred forms of embodiment of my invention:

Figure 1 is an elevational view showing a plurality of heaters, and illustrating the manner in which they are are used upon the head of a subject.

Figure 2 is a vertical sectional view through my preferred form of heater.

Figure 3 is a horizontal sectional View taken substantially on the line 3-3 of Figure 2, looking in the direction of the arrow.

Figure 4 is a sectional viewV taken substantially on the line 4 4 of Figure 2, looking in the direction of the arrow.

Figure 5 is a fragmentary view of the casing, showing a Slightly different form of construction.V

Figure 6 ,iS a view similar to Figure 5,

showing a still tion of the casing.

Figure 'l' is an elevational view of my improved heater, showing a different manner of conducting the lead wires thereinto, and

Figure 8 is a sectional view taken on line 8---8 of Figure 7, looking in the direction of the arrow.

Referring now to the drawing, and particularly to the embodiment of the invention shown in Figures l to 4 inclusive, and wherein similar reference ,characters refer to similar parts throughout the views thereof, the reference numeral l denotes a ring, preferably formed of insulating material, such for instance as wood, hard rubber, balielite, or the like. This ring forms the foundation part of the heater.

different form of construc- 2 indicates a shell having a cylindrically `formed bore or aperture 3, the upper end of the shell being, as shown, outwardly turned or bent so as to embrace the ring l, as clearly shown in Figure 2. 4 indicates the outer shell which, together with the inner shell 3, forms a casing, the walls of the shells 2 and 4 being preferably spaced apart, as shown, so as to form a casing adapted to receive the resistance wire and its lower end of the shell 2 is outwardly flanged as at 5, and the lower end of the shell 4 is bent inwardly and upwardly, as at 6, so as to embrace the lower end of the flange 5. The upper end of the shell 4 is outwardly offset, as at 7, to form an enlarged portion 8, which enlarged portion preferably telescopes the downwardly turned part 9 of the shell2.

The parts 2 and 4 of the shell are then fastened together, as by means of the clamp screws lO, which are threaded through said parts and into the ring l. Thus it will be seen that the shells 2 and 4 are firmly united both top and bottom to form a tight closure for the heating wire and insulating material. The shells 2 and 4 are preferably formed of metal.

Positioned exteriorly of the cylindrically formed portion 3 of the shell 2 is a layer of insulating material ll. and wound about this layer of insulating material, which is preferably mica. or the like. is a layer of insulating wire l2. Several layers of insulating wire, and separated by mica strips, may be positioned upon the shell, such number of windings being provided as necessary for associated insulating material. The

the purposes for which the device is to be utilized.

One terminal of the insulating wire 12 is fastened to the screw 13, and the opposite terminal of said insulating wire is fastened `to the screw 14, which screws are threaded upwardly into the ring 1. Y

The reference numeral 15 denotes a U- shaped handle, preferably composed of a. hollow tube bent into the form shown, the ends of which extend through apertures formed in the upper end of the shell 2, clamp screws, as at 11, being employed to fasten the legs of the handle portion securely 'to the casing. The leading-in wires 17 are conducted as by means of the cable 18 into the upper portion of the handle, and are then separated so that one leading-iii wire passes downwardly along one'leg of the handle portion ,15, and the ot leading-in wire passes downwardly adjacent the other leg of the handle, suitable means being provided for insulating the wires from the handle, and a suitable covering of insulating material 19 being provided to cover the said leading-in wires. Y

Thelower ends of theleading-in wires 20 and 21 are passed through apertures provided in the shell 2 and ring 1, and are joined to the ends of the resistance wire through the medium of theterininal screws 14. Y y v Y By reason of the construction shown, it will be seen that no strain whatever is placed upon the leading-in wires, the resist- V'ance wire, or the point of connection between the leading-in wire 4and the resistance wire, so that the heaters may be readily suspended by the cahles 15 without any danger of the mechanical or electrical connection between the leading-in wires and the resistance wire, thereby insuring' against accidental disarrangement of the heater.

In the embodiment of my invention shown in Figure 5 the construction of the heater is the same as already described, exceptthat tlie outer shell l is spun into'the inner shell 2, as shown at. 22, thus eliminating the use .of the clamp Vscrews 10. Y

In. the embodiment of the invention shown in'Figure 6 the upper end ofthe outer shell 4 is spun into the upper end of the inner shell 2,. as at the point 23, in. this embodiment of the. invention .the outer shell '4 being bent inwardly about the upper end of the shell 2as at 2li.V

Inv theembodiment .of my invention shown in Figures 7 and 8, the construction of the heater proper is identical with that already described, the only difference being that instead of conducting the leading-in wires ,alongl the legs of the handle 19, the cable 15 is securely fastened to the upper end of said handle, the wires, however, passing directly downwardly between the legs of the handle,

to the upper end of the heater, whence they pass through the upper wall of the shell 2, through the ring 1, to the terminal screws 1d.

lt-will accordingly be seen that I have provided a construction well adapted to attain, among others, all the ends and objects above pointed out in an exceedingly simple and e'tiicient manner, and that l have provided-V a heater which can bel used without danger of becomingaccidentally short-circuited, or lotherwise deranged with the C-Onscquent danger of burning or injuring the subject or destroying the hair being treated.

By reason of the shape of the heaters, as indicated in Figure 1, it will be noted' that they nest nicely together with a. minimum of space between adjacent heaters, whereby a relatively large number of heaters may be assembled upon the head of the subject. t

Having thus described my invention what Y I claim as new and desire to secure by Letters Paten-t is:
